BBBBBBBB!!!!! ATOMIC MASSES :D
Answer:
The zero field location has to be on the line running between the two point charges because that's the only place where the field vectors could point in exactly opposite directions. It can't be between the two opposite charges because there the field vectors from both charges point toward the negative charge.

Answer:
Explained
Explanation:
If you are in a rotating system newton's law do not work .Adding a frictious force can make the law work. If an orbiting object is in constant freefall under gravity . Even elliptical planet orbits are examples of freefall under gravity. The force F which the planet feels; this force can be resolved into two components, centripetal force F_C and tangential force F_T.
The tangential force causes an acceleration(newton's second law) which decreases the speed and the centripetal force causes the velocity to turn. In there is circular orbit of radius R, F_T=0 and the centripetal force is F_C=Mv^2/R;
The centrifugal force would be a vector with magnitude Mv^2/R( same as that of centripetal) pointing away from the sun but it does not really exist.
